• The deposition of a High Resistivity Transparent oxide between a Transparent Conductive Oxide and the window Cadmium sulfide has demonstrated the improvement of performance of Cadmium sulfide/Cadmium telluride solar cells, fabricated in the superstrate-configuration. In this work the influence of the Pneumatic Spray Pyrolysis and magnetron sputtering techniques on the properties TCO/SnO_(2)/CdS structure through the deposition of the intermediate SnO_(2) between the commercial conducting glass and CdS window is presented by means of X-ray Photoelectron Spectroscopy, Secondary Ion Mass Spectroscopy, and contact resistance, calculated using Transmission Line Method, in order to reduce the front contact resistance in devices with superstrate-configuration. The results of this work are applicable to other solar cells in the same configuration as the recent solar cells based on the compound Sb_(2)Se_(3), where the use of this type of High Resistivity Transparent has not been studied.
